While campaigns like these get us excited, many of the brands behind these social media successes are still on the road to maintaining a consistent social presence, above and beyond a one-hit-wonder promotion. There are a handful of brands, however, that continue to awe us with social media wins one after another, while incorporating their communities and core brand values, and actively participating across multiple platforms, including Facebook, Foursquare, Twitter, and YouTube.

In appreciation of engagement, innovation and longevity, here are five of our top picks for must-follow brands that just know how to use social media. Let us know which brands you enjoy following across your various social platforms in the comments below.

Why Starbucks Rocked This Year: As the most-"Liked" brand on Facebook and one of the top 10 most followed brands on Twitter, Starbucks has proven it's social media savvy. It has continued to launch new campaigns and engage followers along the way. And it continues to source ideas from its custom social network, My Starbucks Idea.

But how many brands can say they've actually driven sales and store traffic? Starbucks is one of those brands that has measured real value. During its Free Pastry Day, Starbucks logged more than 1 million visitors to its stores and attributed the success to digital and social spaces.

Why You Should Follow: Starbucks continues to push the technological envelope when it comes to the digital and social spaces. This year it rolled out the Starbucks Card Facebook app, where users can buy their friends Starbucks via Facebook, and it announced the store's digital network, an exclusive content network curated by the company and designed to enhance the customer’s in-store experience. We have a feeling that the fun has only just begun.

Why JetBlue Rocked This Year: Last year, corporate communications manager Morgan Johnston told Mashable, "Our goal would be to make ourselves available, help whenever possible, and to show that our brand is built by real people who care about our customers." Johnston was discussing JetBlue's Twitter strategy, and we'd have to say it looks like it has had success in being there for its customers. Taking a look at the JetBlue Twitter stream, you see a mass of responses from the airline to inquiring followers — that's what social is all about. Even with the occasional flight attendant snafu, the company manages to handle the social space well.

We also love all of the flight deals that JetBlue shares via Facebook and Twitter. We've read over and over that one of the top reasons why people follow brands via social media is that they want inside information on promotions and deals. We're always tuned in to what JetBlue has to say, even if just for the limited offers on All-You-Can-Jet passes that pop up every now and then.

Why You Should Follow: Flight deals — get 'em while they're hot! Thanks to social media, and especially Twitter, the latest All-You-Can-Jet offer sold out in 36 hours. You've got to be on the ball these days if you want to get a great flight deal. Social media is the way to go, and JetBlue is one of our favorites.

Typically, Foursquare tips are used to uncover insider information when you check in to a venue. The History Channel rethought the concept of the tip and began providing unexpected history lessons that were tied to locations. We love that the company innovated and built upon its brand's core competency.

The History Channel's other social media properties, including YouTube, Facebook and Twitter, also built on its competency by serving history lessons. One of my favorite features is the daily "This Day in History" update that goes out on Twitter and Facebook.

Why You Should Follow: Get your education on! The History Channel doesn't have to try to hock products because what they offer is compelling enough — knowledge. It's cliche, but true: Knowledge is power. Enough said.

Why Whole Foods Rocked This Year: Whole Foods takes the cake for having one of the most expansive and inclusive social media strategies around, making it one of the top enterprises using social media. The company encourages individual stores and regional areas to create their own Twitter handles for a more niche customer experience online, and it even fosters topical tweets on subjects like wine and cheese. At our latest count, the company had nearly 300 niche Twitter accounts. That's dedication.

Besides an amazing Twitter presence, the company also runs a Facebook Page and blog — both of which host recipes, health tips and company news updates, especially regarding its social good efforts.

Why You Should Follow: If you're a Whole Foods junkie and want/need local updates on your neighborhood Whole Foods store, the company probably has a Twitter handle for you to follow. Furthermore, no matter where you live, you can always get great recipes from the company's blog or Facebook Page, or even the automated Twitter handle dedicated to recipes. While Twitter is all about interaction, sometimes an automated feed with valuable information can be a great resource.

Why Dunkin' Donuts Rocked This Year: Dunkin' Donuts is all about highlighting its customers via social media. It is always running social media contests, such as last year's "Keep It Coolatta" sweepstakes, the recent "Create Dunkin's Next Donut" contest and the current "Ultimate DD Coffee Fan" search. On Facebook, the brand also currently features a "Troop of the Week" as its Page profile picture, showing its support for America's heroes, as part of a larger partnership with the USO.

Why You Should Follow: Dunkin' Donuts focuses on showcasing passionate fans. If you're not a DD nut, just walk away. But if you're a huge advocate for the company, you'll probably have your chance at Dunkin' fame by staying up to date on its latest contests.
